Grandpa Neuer on 21 million is insane.
Probably. And his mistake vs Real Madrid probably cost them the game and a chance to win the Champions League.
But he was absolutely spectacular in general vs Real Madrid and they would have gotten blown out if it wasnt for him if he didnt make 3 or 4 spectacular saves before that mistake --- not to mention he was again very good for Germany in the Euros (with his late save vs Switzerland especially standing out to me).
He may be overpaid and past his prime, but he's still very good. If Buffon was overpaid his final years with Juve, no one would care, because he had an amazing career for the club and was still good, even if not in his prime anymore.
Of that list, Neuer's wages are amongst the least offensive. Muller (although that feels iike more of a thank you and goodbye to a club legend type contract), Goretzka, and Gnsbry stand out as being the worst. Sane is also massively overpaid, but he's also probably their best winger and still a quality player.
